Associated Spring Raymond 104-408 Die Spring Red

Product Description

The ASSOCIATED SPRING RAYMOND 104-408 is a medium heavy-duty die spring designed for use in stamping dies, punch presses, and other tooling applications that require consistent, high-cycle compression force. It features a 3/4 inch hole diameter and a 3/8 inch rod diameter, with a 2 inch free length. The trapezoidal wire shape provides a higher load capacity per unit length compared to round wire springs, delivering a maximum deflection load of 183.5 pounds at 0.74 inches of maximum deflection. The red color coding identifies it as a medium heavy-duty grade per industry standard classification. Toolmakers, die setters, and maintenance machinists are the typical installers of this component.

This die spring is suited for use in metal stamping dies, injection mold tooling, jigs, and fixtures across light industrial and heavy manufacturing environments. The compact 2 inch free length makes it appropriate for applications with limited pocket depth. It is sold individually and fits standard die set guide rod configurations using a 3/8 inch rod. It is manufactured to ISO 9001:2008 and ISO/TS 16949:2009 quality standards, making it suitable for precision tooling in automotive and general industrial production settings.

Key Features

• Medium heavy-duty rating with 183.5 pound maximum deflection load
• Trapezoidal wire cross-section for higher load capacity versus round wire designs
• 240 lb/inch spring rate for predictable, consistent force output
• Chromium alloy steel construction for durability under high-cycle conditions
• Red color coding for quick visual identification of duty class
• Manufactured under ISO 9001:2008 and ISO/TS 16949:2009 certified quality systems

Compatibility

Designed as a standard die spring for use with 3/8 inch guide rods in tooling pockets requiring a 3/4 inch hole diameter and a 2 inch free length.

Installation Notes

Die springs are installed by toolmakers and die maintenance technicians. Always de-energize and lock out all press energy before servicing die components. Ensure the spring pocket depth and rod clearance are appropriate for the selected free length and maximum deflection range. Do not compress the spring beyond the rated maximum deflection, as over-compression will reduce service life and may cause spring failure.
